Having lived through a few since the first I noticed in the 70s we are preparing for it.
In the 70s my parents were reduced to taking the pennies out of our piggy banks. We were well stocked with candles, which were used regularly in the blackouts and we learned a lot of food stretching skills, ate foods we may not have wanted to.
In the 80s we clung on to our one bed flat, watched a number of friends hand their keys back to their mortgage lender (somehow this is never believed by some on MN). We were in our mid 20s and all had new mortgages, were persuaded it was best to own, rents were often much higher than mortgages, rates were low.
We all took advantage of 0 £ deposits and those low rates. DH and I worked nmw jobs and worked out an entirely arbitrary 20% interest rate, we would be able to afford it, so we bought. Rates got very close very quickly!
90s we didn't notice. We couldn't sell our tiny flat, not even give it away. So we both went to Uni, spent the decade on one wage and then, as house prices rocketed, sold the flat and went back to renting. We only bought again about 4 years ago.
So we have some idea what to expect. Our prepping so far consists of checking all outgoings and losing those we don't need, reducing those we can. When shopping gets more normal we will stock up tinned good, dried pulses, oats etc. Candles if course, and I'll trawl charity shops for fabrics, bedding, large size clothing etc. I see so will go back to making basic clothing. Learning how to sew and modify clothes is a good move. It's really very easy and a good second hand machine can be really cheap.
A second freezer can be a godsend, especially if you have kids. It makes bulk cooking much easier, but beware power cuts. You soon learn that the inside of a washing machine stays nice and cold!!! I'll also be looking in charity shops for cold bags, just in case!
Apart from that it's all in your mindset. If you can persuade yourself that every hardship, every lack, is a challenge that is educational, fine even, you might find that you don't get drowned by it.
I have a coupe of friends who are catastrophising, they are bloody miserable. I suspect one of them will cut me loose as a friend as I can't share her absolute dread and am just looking for work rounds and coping mechanisms for what we are living through now and the probable repercussions. We have very similar lives and incomes levels, except I am self employed and wouldn't expect my job to survive a recession.
I'm not saying a positive mental attitude fixes anything, but any vestiges of one makes working your way through scary shit a little bit easier.
I'm sure the Prepper threads will proliferate soon enough, so we can all ask questions and share our thoughts and solutions.
